Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

if you pick one marble at random, the odds are 17/(42+17+27) or 17/86 or about 20%
What is the probability that you get a tail on the coin given you got the number 5 on the die?
It is 0.5 becasue the events are (or should be) independent.
What is the probability that a specified seeding has no neighbors within 1 meter?
The answer will depend on the density of the seedlings and their distribution - in 2-D space..
the probability of the offspring for a second generation.
What are the chances of being pregnant with twins if your husband is an identical twin himself?
The same as anyone else. No genetic marker has been found yet related to identical twins.
And how does this relate to coins?
What is a probability is based on repeated trials of an experiment?

TRUE
What is the probability of drawing a number card from a standard 52 deck cards?
If we're talking cards of all suits 2-10 then there are 36 number cards. That would then be 36/52 which would be 69.2 percent of the time.
What do you mean by Statistics?

Does a normal probability distribution include a bimodal distribution?
No, the normal distribution is strictly unimodal.
the odds theoretically are almost infinity to 1 as they could be any color. -------------------------------------------------------------------------------------------
2nd opinion
Let's say we have 3 boxes with 4 balls each.
Box A has 4 white balls.
Box B has 3 white balls.
Box C has 2 white balls.
The probability of drawing 2 W balls from;
Box A, P(2W│A)=
(4/4)∙(3/3)=
1
Box B, P(2W│B)=
(3/4)∙(2/3)=
1/2
Box C, P(2W│C)=
(2/4)∙(1/3)=
1/6
Say the probability of picking any of the 3 boxes is the same, we have;
P(A)=
1/3
P(B)=
1/3
P(C)=
1/3
Question is, given the event of drawing 2 W balls from a box taken blindly
from the 3 choices, what is the probability that the balls came from box A,
P(A│2W).
Recurring to Bayes Theorem:
P(A│2W)=
[P(A)P(2W│A)]/[P(A)P(2W│A)+P(B)P(2W│B)+P(C)P(2W│C)]=
[(1/3)(1)]/[(1/3)(1)+(1/3)(1/2)+(1/3)(1/6)]=
6/10=
0.60=
60%
P(A│2W)=
0.60=
60%

32.6% or 67.4% depending on what probability you want.
What are the odds of getting shot at school?
Take everyone shot at school
divided by everyone that has gone to school
and you have a rough estimate of your odds of being shot at school, which is most likely extremely small.
